Text-to-image generative models have demonstrated remarkable capabilities in synthesizing visual content from natural language prompts, yet they systematically encode and amplify cultural biases inherited from training data dominated by Western-centric internet sources. This paper proposes a reinforcement learning-based framework for cultural alignment that steers model outputs toward safety and inclusivity without sacrificing generation quality or creative diversity. We conceptualize cultural alignment as a multi-objective optimization problem where reward signals are derived from culturally aware human feedback, structured fairness metrics, and adversarial robustness criteria. The proposed approach integrates a modular reward architecture that decouples universal safety constraints from culturally specific appropriateness norms, enabling fine-grained control over representation across different demographic and regional contexts. We examine structural trade-offs between alignment granularity and computational overhead, and discuss the implications for model governance, deployment scalability, and long-term sustainability. Through comparative analysis with existing debiasing and fine-tuning methods, we highlight the advantages of reinforcement learning strategies in maintaining model fluency while correcting systematic cultural omissions and stereotypes. The paper also addresses infrastructure requirements for collecting diverse human preference data, the risk of reward hacking in culturally sensitive domains, and the necessity of continuous monitoring for concept drift. We conclude by outlining policy recommendations for inclusive model development and propose a research agenda for cross-cultural evaluation benchmarks. This work aims to bridge the gap between technical alignment techniques and socio-technical considerations, offering a pathway toward generative AI systems that respect cultural pluralism.
